long-headed coneflower

thimbleflower

The leaves Ratibida columnifera are concentrated at the bottom of the plant. They are deeply divided into long, narrow segments, and are finely pubescent giving them a grayish cast. The stems are also finely pubescent, often branched, and are typically 2' tall but can grow up to 3'. The flower heads are composed of drooping petals that can vary in color from yellow to red, and can also be multi-colored. They surround a columnar central disk that can be 1/2" to 2" long. This unusual flower configuration has earned the species the common name Mexican hat, which it is said to resemble.

Cultivation

Upright prairie coneflower, is a clump-forming prairie wildflower, which is widely distributed in North America from Mexico well into Canada. It is both cold hardy and drought tolerant. It is very easy to grow in well-drained soils, in full sun. It is best grown in tight groups because its thin foliage gives the plant a sparse look. Perfect for rock gardens and sunny borders. Ratibida columnifera enjoys a long blooming season that can begin as early as June (depending on location), and extend for 3 months, well into August. Zones 3-9

Propagation

Very easy to propagate from seed. As a matter of fact, it will self-seed readily, often establishing itself beyond its original location. However, its spread can be easily controlled by deadheading, and the species is not considered weedy or invasive. Propagation by clump division is possible, but difficult due the plants' deep tap-root.

Additional Notes

Ratibida columnifera is very attractive to a variety of pollinating insects. Both flower heads and leaves have been used to make medicinal infusions, said to relieve a variety of aches and pains, ranging from poison ivy and rattlesnake bites, to stomachaches, headaches, coughs and fevers.
